Featured Reviews

Aswini Atibudhi - PeerSpot reviewer
Provides real-time data insights with high flexibility and responsive support
The basic challenge for ClickHouse is the documentation, which isn't ideal, but it's mature and stable with more columnar storage, compression, and parallel processing, making it the best for OLAP. In terms of improvements, it's not designed for very frequent small writes, making it less scalable in write-intensive workloads, and it's not flourishing in transactional use cases or when ingesting streaming data, such as batching or buffering, which is something ClickHouse will improve.
Arucy Lionel - PeerSpot reviewer
A simple solution that has very good documentation and low research consumption
LanceDB is deployed on-cloud in our organization. I have only utilized the community-specific version. They have a server-client version that might actually be useful for a lot of other people. I just needed the direct one, which works quite well for me. I don't know how good the server client version is yet. Overall, I rate LanceDB a nine out of ten.
